BOX AND mn'rnon or MAKING THE SAME.

Application filed February 7, 1923. Serial No. 617,425.

To all whom it may concern:

Be it known that I, HARRISON B. WALTER, a citizen of the United States, and a resident of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Boxes and Methods of Making the Same; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon,

which form a part of this specification.

This invention relates to improvements in boxes made of fiber or paper board or the like, and consists of the matters hereinafter described and more particularly pointed out in the appended claim.

The object of the invention is to produce a collapsible box'of the kindknown as a top loading as distinguished from an end loading box, in which the top closure is capable of such attachment to the body, when closing and sealing the box that this attachment may be accomplished not only quickly, so as'to result in rapid handling of the box after'it is packed, but also by .means of the sewing process described in Letters Patent No. 1,449,467 issued to me on the 27th day of March, 1923. The box is of special advantage to those doing a large volume of business requiring rapid packing and handling, in that the sealing maybe carried on upon a plurality of boxes in succession,-- the boxes being advanced-to the sewing position on a continuous moving belt or other conveyor.

The improved box requires a minimum of stock and may. be made at low cost of ma-' terial and labor. Its several advantages will appear more fully as I proceed with my specification. In the drawings Fig. l is a perspective view of the improved box. 7

Fig. 2 is a view representing a partial section through the box in a plane indicated by the line. 2-2 of Fig. 1.

Fig. 3 is a plan view of a blank-for making the body of the box.-

Fig. 4 is a plan viewof'the blank-for the l 7 ends of the box.

' 10 indicate the sides of the box; 11, the

bottom of the box; 12, 12, the ends of the box; and 13 indicates the top closure.

The body of the box is made, as shown,

from an elongated blank (see Fig. 3) of approximately a width equal to the intended length of the box. This blank is cut and creased to provide the part 11 for the bottom of the box, two parts 10, 10 at each side thereof for the sides of the box, a part 13 at one end of the blank for the top closure of the box, and, preferably a short flap extension 13 at the other end of the blank.

The blank is creased transversely on parallel lines 14 to define the several parts mentioned. The blank is also creased longitudinally on parallel spaced lines 15 which define the length of the box body-forming made of the samewidth as the other lateral extensions of the blank. :The flap extension 13 at the other end of the blank is out somewhat shorter than the distance between the longitudinal crease lines 15, 15.

The ends of the box each consists of a blank of an area equal to the cross sectional area of the box, and of a top fla extension 12* defined by a crease line 12. he flap extensions 12 of the end parts 12, as well as the extensions 13 of the top closure part 13, are bevelled at their ends as indicated respectively at 12 and 13.

To form the box, the body blank (shown in Fig. 3) is bent into box form with the bottom 11 horizontal and the sides 10, 10 in vertical relation thereto. An end blank 12 is then brought into the required relation, with its edges coinciding with a crease mark 15 at one side of the body blank. The extensions 11 and 10 respectively, of the bottom and side forming parts of the blank are folded against-the end blank (as shown- -a ainst the outer face ofsaid end blank).

T e 'side'extensions are then attached to the said end blank by means of the fiber lock cal position (being ready to be folded down into a horizontal position) and with the top closure part 13 and the short flap extension 13 (when the same is used) laid back to open up the box.

The box is then loaded. After loading, the flap 13 and the flap extensions 12*, 12 of the ends of the box are turned down and the top closure 13 is folded down against said several flaps to close the box, the same extending entirely across the open top of the box and providing a completeclosure therefor. As fast as the boxes are loaded they may be placed on a suitable conveyor and advanced in succession to sewing machines or other devices adapted to sew by means of a continuous thread or cord the extensions 13, 13 of the top closure 13 to the flap extensions 12, 12 of the ends. This'seals the box at the ends. As the top closure 13 extends completely across the box and as there are no laps or folds in the top closure intermediate the sides of the box, no obstruction or impediment is presented to the operation of the sewing machines, which are thus enabled to apply the sewed joint with smoothness and continuity, proceedin from one box to the next in succession as t e boxes are brought into sewing position by the conveyor. The improved box is thus of great advantage where the top closure is to be attached and sealed in this manner.

Generally, and preferably, a sealing strip 16 is applied at the free edge of the top closure 13 to seal said closure along said edge to theproximate side 10. The flap 13 protop closure of the box.

vides a supplemental support for the top closure along said edge and'a strengthening brace for the corners of the box at said edge. The folding extensions 12 which provide the seats for the top closure and the end extensions 13 of said top closure, provide, after they are attached together, projecting end hand holds or grips at the top of the box, which are convenient in lifting and handling the box. By reason of the inclined parts 12 and 13 at the ends of the respective extensions 12 and 13", projecting corners are eliminated.

While in describing my invention I have referred to several details of construction and mechanical arrangement, it isto be understood that the invention is not thereby in any way limited except as may be pointed out in the appended'claim.

I claim as my invention A box made of blanks of fiber, paper board or the like, comprising a blank cut and creased to provide a bottom, sides and a single top closure flap, the sides and bot tom having foldable and extensions and the top closure flap having non-folding end extensions, and blanks cut to form the ends of the box and having top foldable extension flaps; said first named blank being folded to form the main body of the box and having the end extensions of its sides and bottom folded against and secured to the sides and bottom parts of said end blanks by means of a joint which includes cement and the distortion of parts of the extensions into the body of the blanks forming the ends, and the extensions at the top of said end blanks being adapted to be folded down to extend outwardly from the box to form seats in the plane of the top of the box to receive and to be attached to the extensions of the single In testimony that I claim the fore oing as my invention, I afiix my signature t is 31st day of January, A. D. 1923.
